Improvement in garden-pumps



CARL G. KORTE, OF GARLSTADT, NEW JERSEY.

IMPROVEMENT INv GARDENPUMPS.

Specification forming part of Letters Patent No. 124,593, dated March12, 1872.

ing drawing forming part of this specication,

in which drawing- Figure 1 represents a perspective 4view of my pump.Fig. 2 is a longitudinal section ot' the same.

Similar letters indicate corresponding parts.

This invention consists in the arrangement on a pump-barrel of ashoulder-brace, which forms the bearing for the fulcrum-pin of thepump-lever, and also serves to conline the throw of the pump-leverwithin the proper limits. From the lower head of the pumpbarrel projectsa pointed foot, which forms the chamber for the foot-valve, in suoli amanner that, by placing the pump-barrel into a pail and bringing thearm-pit to bear upon the shoulder-brace,the pump can be operated withgreat ease and convenience; With the pump is combined a iexible tube,which is connectedto the pump by means of a tapering nipple and sleeveand the same means are employed for the purpose of securing themouth-piece in the end of said tube.

In the drawing, the letter A designates the barrel of my pump, the lowerhead of which is provided With a chamber, a, containing the foot-valveb, said chamber being formed with a sharp-pointed foot, c, so that thebarrel, when placed into a pail or tub, will be prevented from slipping.Through the flanges at both ends of the barrel and through the headsextend rods dd', Which unite at the top and form a shoulder-brace, B, ata convenient height to reach under the arm-pit of the person intendingto operate the pump, as shown in Fig. 1. The rod d forms the bearing forthe fulcrumpin e ofthe lever O, which connects, by a pivot, f, with thepiston-rod D, and which extends through a recess, g, in the rod d, sothat the ends of said recess form stops which confine the motion of thepump-lever within certain limits and prevent the piston from coming incontact with either of the ends or heads of the" pumpbarrel. From thevalve-chamber a eX- tends a pipe, E, which connects, by a nipple, h,with4 a flexible pipe, F. The nipple h forms a chamber for the valve t',and it is provided at its outer end with an internal screw-thread toreceive a conical pipe, j, the diameter of which increases toward itsouter end. This pipe is forced into the end ofthe iiexible pipe F, and aconical sleeve, k, is forced over it, so as to compress the end ofthepipe F between it and the conical pipe j, and to form a tight jointbetween said iiexible pipe and the nipple h. In the outer end oftheiiexible pipe F is secured a mouth-piece, Z, the diameter of whichincreases toward its inner end, so that, when the same is forced intothe flexible pipe, it can be locked by a conical cap or sleeve, nl, asshown in Fig. 2.

The great advantage of this pump is that it can be conveniently carriedand placed into a pail in any place Where it is desirable to use'thcpump, all by V one person, Without requirin g any aid or preparation. Incase of tire it serves to bring the Water to bear ou the place where itis required, since one person can easily carry a water-pail and one ofmy pumps as close to the iire as the temperature will permit. My pumpmay, however, also be used for sprinkling in gardens or lields, and forany purpose Where pumps are generally used.

What I claim as new, and desire to secure by Letters Patent, is`

1. The arrangement of a shoulder-brace, B, and pointed foot c on thebarrel A of a pump, said brace forming the bearing for the fulcrumpin eof the lever O, substantially as shown and described.

2. An improved pump, consisting of a shoulder-brace, B, recess g, leverG, piston-rod I), barrel A having a foot, c, valve b, valve-chamber a,discharge-pipe E, valve 1', and pipe F, and its connections,substantially as set forth, for the purpose specified.

This specification signed by me this 28th day of December, 1871.
